==3397== Syscall param rt_sigaction(act->sa_mask) points to
uninitialised byte(s)
==3397==    at 0x18F417: __libc_sigaction (in /lib/libc-2.13.so)
==3397==    by 0x8052CCE: main (jam.c:273)
==3397==  Address 0xbefc073c is on thread 1's stack

The code is:

 77009 noel_belcourt #if defined(unix) || defined(__unix)
 77009 noel_belcourt     sigset_t sigmask;
 77009 noel_belcourt     struct sigaction sa;
 77009 noel_belcourt
 77009 noel_belcourt     sigemptyset(&sigmask);
 77009 noel_belcourt     sigaddset(&sigmask, SIGCHLD);
 77009 noel_belcourt     sigprocmask(SIG_BLOCK, &sigmask, NULL);
 77009 noel_belcourt     sa.sa_flags = 0;
 77009 noel_belcourt     sa.sa_handler = child_sig_handler;
 77009 noel_belcourt     sigaction(SIGCHLD, &sa, NULL);
 77009 noel_belcourt     sigemptyset(&empty_sigmask);
 77009 noel_belcourt #endif
 77009 noel_belcourt
